When i get a laptop backpack, i wanted to get a sling style shoulder back pack. I was wondering whenyou're in college, will i need a backpack taht carries a lot of textbooks (or even 1 or two textbooks) when i go to class? I don't want to get a messenger style laptop bag, but more of a backpack kinda thing. The Tom Bhine Buzz backpack looks nice, but its really small and i dunno if it'd hold many of my essentials. Thanks.
